Each black circle and red cross on the upper image map is a quasar similar to this one. The Huge Large Quasar Group , ( Huge-LQG , also called U1.27 ) is a possible structure or pseudo-structure of 73 quasars , referred to as a large quasar group , that measures about 4 billion light-years across.
A large quasar group (LQG) is a collection of quasars (a form of supermassive black hole active galactic nuclei) that form what are thought to constitute the largest astronomical structures in the observable universe. LQGs are thought to be precursors to the sheets, walls and filaments of galaxies found in the relatively nearby universe. [1]
This is a list of the largest cosmic structures so far discovered. The unit of measurement used is the light-year (distance traveled by light in one Julian year; approximately 9.46 trillion kilometres). This list includes superclusters, galaxy filaments and large quasar groups (LQGs). The structures are listed based on their longest dimension.
At a distance of more than 13.03 billion light years from Earth, J0313–1806 is the most distant— and thus the most ancient — quasar yet seen by astronomers. Astronomers just detected the ...
Spectrum from quasar HE 0940-1050 after it has travelled through intergalactic medium This view, taken with infrared light, is a false-color image of a quasar-starburst tandem with the most luminous starburst ever seen in such a combination. Quasars also provide some clues as to the end of the Big Bang's reionization.
